Answer:
Methanol would be used as a reagent in excess, since it is a very low-cost solvent. For product isolation, the first thing to do is remove the methanol through a distillation process. The residue produced can be dissolved in diethyl ether. Using a NaHCO₃ solution, extraction is performed. When it separates into two phases, the product will be in the ether and the reagent in the aqueous phase. The ether can also be removed by distillation, and at the end of this process you will have the product you want.

Answer:
2.835 moles of carbon
Explanation:
By definition, there are 6.022x10^23 atoms (or compounds) in one mole.
Write and use this as a conversion factor:
(6.022x10^23 atoms)/mole
(1.707 x 10^24 atoms of carbon)/((6.022x10^23 atoms)/mole) = 2.835 moles carbon
Alkynes are hydrocarbons with at least one triple covalent bond.
